public offering price range has been determined, we will update our filing to include the number of additional shares of restricted
common stock expected to be issued, based on the mid-point of such estimated initial public offering price range, assuming all
holders of unvested Class B Units elect to replace their unvested Class B Units for shares of restricted common stock of the Company,
which is more fully described in the revised disclosure.</P>

refer to Tables 1 and 2 below. The significant decrease in both the total net operating loss carryforwards and related amounts
of gross deferred tax assets was principally driven by a true-up to the carryforward for Certara LP (Portugal), which had a deferred
tax asset measured at 5%. The effect of this decrease was less than the net increase to carryforwards for other foreign jurisdictions,
all of which had a valuation allowance. Also, in 2019, the Company recorded a partial valuation allowance in the amount of $742 against the deferred tax asset for U.S. federal net operating loss (which when added to the foreign balance of $4,443 in Table
1, aggregates to $5,184, as shown in Table 2).</P>
